شرطی اول: شرایط منفی (اگر تو انجام ندهی...)
Grammar Rule in 30 Seconds
Use negative first conditionals to describe future consequences of NOT doing something right now.
- Use 'don't' or 'doesn't' in the 'if' part: 'If you don't hurry...'
- Use 'will' or 'won't' in the result part: '...you will be late.'
- You can replace 'if... not' with 'unless': 'Unless you hurry...'
مرور کلی
این گرامر چطور کار میکنه
If) و نتیجه (بخش Will). در شرطی نوع اول منفی، ما معمولاً کلمهی «نه» یا «منفیساز» رو توی بخش شرط میذاریم. این کار یه مانع مشخص ایجاد میکنه. فقط اگه *نتونیم* از روی اون مانع بپریم، نتیجه اتفاق میافته.- بخش شرط یا If-Clause: اینجا از زمان Present Simple استفاده میکنیم. با اینکه داریم دربارهی آینده حرف میزنیم، ولی زمان حال رو به کار میبریم. این قانون شماره یک هست که خیلیها رو به اشتباه میندازه. اینجا از
don'tیاdoesn'tاستفاده میکنی. - بخش اصلی یا Main Clause (نتیجه): اینجا از Future Simple استفاده میکنیم (
willیاwon't). پیامد ماجرا همینجا قرار میگیره.
unless بچرخونی. کلمهی unless مثل یه میانبر زبانی برای if... not هست.Unless you invite me, I won't go). اینطوری جمله تمیزتره، مثل فعال کردن حالت دارکمود روی گوشی—کلاً حس بهتری میده.

کی استفاده کنیم
- مذاکرات: «اگه قیمت رو پایین نیاری، این ژاکت وینتیج رو نمیخرم.» این حرکتِ قدرتیِ توی جمعهبازاره.
- هشدارها/تهدیدها: «اگه فیلم جدید مارول رو اسپویل کنی، بلاکت میکنم.» همهمون توی این شرایط بودیم.
- فومو (FOMO): «اگه الان بلیط نخریم، تموم میشه!» این همون روشیه که اپلیکیشنها یادت میدن ساعت ۳ صبح پول خرج کنی.
- مشکلات تکنولوژی مدرن: «مگه اینکه وایفای بهتر بشه، وگرنه نمیتونم به تماس دیسکورد وصل بشم.»
- برنامههای اجتماعی: «اگه تا ظهر جواب نداد، بدون اون میریم ساحل.»
اشتباهات رایج
- استفاده از 'will' در بخش شرط: این رایجترین اشتباهه. مردم دوست دارن بگن "If it won't rain...
. نه! همینجا استپ کن. بعد از
If it doesn't rain". بهifیاunlessحتماً باید از زمان حال استفاده کنی. درستش اینه:ifمثل یه «منطقه عاری ازwill» نگاه کن. - منفیِ مضاعف با 'Unless': کلمهی
unlessخودش به معنی «اگر نه» هست. پس دیگه به یهdon'tدیگه نیاز نداری. - ✗ Unless you don't study, you'll fail. (این یعنی: اگه درس بخونی، میافتی. گیجکننده شد!)
- ✓ Unless you study, you'll fail.
- تطبیق فاعل و فعل: یادت باشه که
heوsheوitبهdoesn'tنیاز دارن، نهdon't. جملهی "If he don't go« خیلی غیررسمیه و در اکثر جاها از نظر گرامری غلطه. بگو: »If he doesn't go". - گیج شدن در ویرگول: اگه بخش
Ifاول بیاد، به ویرگول نیاز داری. اگه بخش «نتیجه» اول بیاد، ویرگول نمیخواد. - ✓ If you don't call, I'll worry.
- ✓ I'll worry if you don't call.
مقایسه با الگوهای مشابه
- شرطی نوع صفر در مقابل نوع اول: نوع صفر واسه حقایق کلیه (اگه به گیاهها آب ندی، خشک میشن). نوع اول واسه یه موقعیت *مشخص* در آیندهست (اگه امروز به *این* گل آب ندی، خشک میشه). نوع صفر «همیشه درسته»؛ نوع اول یعنی «ممکنه این اتفاق بیفته».
- شرطی نوع دوم: این واسه چیزهای خیالیه. «اگه مجبور نبودم کار کنم، کل دنیا رو میگشتم.» (اما مجبورم کار کنم). شرطی نوع اول اینه: «اگه امروز کار نکنم، حقوق نمیگیرم.» (این یه نگرانی واقعیه!).
- If not در مقابل Unless: کلمهی
unlessمعمولاً به یه استثنا اشاره میکنه که نتیجه رو تغییر میده. «من ساعت ۵ اونجام، مگه اینکه ترافیک بد باشه.» اینجا روی تنها چیزی که میتونه برنامه رو خراب کنه تمرکز شده.If... notکلیتره و در هشدارها رایجتره. "If you don't stop, I'm calling the police« خیلی جدیتر از »Unless you stop..." به نظر میرسه.
سؤالات رایج
میتونم به جای will از might استفاده کنم؟
صد در صد! "If I don't finish this, I might miss the party." این یعنی فقط ۱۰۰ درصد دربارهی نتیجه مطمئن نیستی.
آیا unless همیشه با if not قابل جابهجاییه؟
اکثر اوقات بله. اما unless برای چیزهایی که کاملاً غیرمنتظره یا کلاً منفی هستن یه کم عجیب به نظر میرسه. ما معمولاً زمانی از unless استفاده میکنیم که شرطمون یه سناریوی «مگر اینکه» باشه.
آیا خودِ انگلیسیزبانها همیشه این قوانین رو رعایت میکنن؟
اکثراً بله، اما در اصطلاحات خیلی عامیانه ممکنه بشنوی که کسی بعد از if از will استفاده کنه، که البته معمولاً معنیش عوض میشه و به «اگه مایل باشی که...» تغییر میکنه. واسه سطح B1، همون قانون «منطقه عاری از will» بعد از if رو بچسب!
میتونم شرطی نوع اول منفی رو به صورت سوالی بپرسم؟
بله! "What will happen if you don't pass?« یا »Will you be sad if she doesn't come?". فقط حواست باشه که don't/doesn't توی بخش شرط بمونه و will توی بخش سوالی بیاد.

تله "Will"
will یا "won't« رو توی قسمتی از جمله که با »if« یا »unless« شروع میشه، استفاده نکن. این قسمت همیشه زمان حال سادهست. مثلاً نمیگی: »If it won't rain«, بلکه میگی: »If it doesn't rain, we'll go.""Unless" یعنی "اگر نه"
unless گیج میشی، اول جمله رو با if... not بنویس، بعد به جاش unless بذار. این کار از دوتا منفی پشت سر هم جلوگیری میکنه. مثلاً: "If you don't hurry, we'll be late.« میشه: »Unless you hurry, we'll be late."هشدارهای مودبانه
Unless گاهی وقتها یه کم مودبانهتر یا شبیه یه پیشنهاد ملایم به نظر میاد تا "if you don't«. مثلاً وقتی میخوای یه چیزی رو پیشنهاد بدی: »Unless you object, we'll proceed."Smart Tips
Start with the 'If' clause to make the warning more direct and urgent.
Use contractions like 'don't', 'doesn't', and 'won't' in speech. Full forms sound very robotic.
Mentally replace it with 'If... not' to check if the sentence makes sense.
Read the sentence aloud. If you naturally pause after the first part, you probably need a comma.
تلفظ
Contraction Stress
In negative conditionals, the 'don't' or 'won't' is often stressed to emphasize the condition.
Rising-Falling
If you don't go (rising), I'll be sad (falling).
The rising tone on the if-clause signals that the sentence is not finished.

سوالات متداول (8)
No. You should only use `won't` in the result clause. The if-clause must use `don't` or `doesn't`.
Yes, `unless` often sounds slightly more formal or emphatic, especially in writing.
In casual writing, people might not notice. However, in formal writing, it is a punctuation error if the `if` clause comes first.
Yes! Use `might not` if you are less certain about the result. 'If you don't study, you might not pass.'
This is a rule in English for all time and conditional clauses (using if, when, before, after). The condition is treated as a present fact.
Usually no. `Unless` means `if not`, so `unless you don't` means `if not you don't`, which is a confusing double negative.
In some very informal dialects or songs, you might hear it, but in standard English and for exams, it is always `doesn't`.
No. The first conditional is only for possible future events. For the past, you need the third conditional.
